Sources we read

The rules and folklore on this site cite 326 sources from 41 publishers. A person has read 190 of them. The rest were fetched and quoted when the claim was written, and every page that cites one says “Accessed” beside it until a person reads it.

Of the 261 sources the rules cite, 242 are university extension guides, 11 are peer-reviewed studies and 8 are government and other publications. Extension guides are written by university specialists from the research, so they are good sources, but they are a step away from the trials themselves: 3 of the 97 source-checked rules graded Well established or Promising cite a study directly.
